The ISMRM 2006, in Seattle, Washington, USA, disclosed a bipartite device that allows a patient to be supersonically MR-backed on the back of a supine biopsy at the International Society for Magnetic Resonance in Medicine Store patient table (Abstract "MRI-guided prostate biopsy in two different standard 1.5 T scanners using an endorectal biopsy device", Proc. Intl. Soc. Mag. Reson. Med. 14 (2006), page 1446
; and accompanying poster). However, the patient must slide on the patient support table into the patient tunnel with his feet first until a helper standing behind the magnet of the magnetic resonance device can grasp the patient's legs and hold it upright. Then, from the side of the helper, a storage part arranged at this end of the magnetic resonance apparatus is inserted and connected to the patient table. Thus, a storage system of two separate parts (patient support table and storage part) is formed. The patient's legs are placed on the storage part for insertion of an endorectal examination device. This process is effortful for both the helper and the patient. The effort will be greater the more weight the patient's legs have and depending on the support that the patient can or must deliver to the helper. The introduced at the ISMRM 2006, introduced from behind into the magnetic resonance device storage part can be retracted only to a certain extent in the magnetic resonance device. In particular, it is not possible to extend the patient table and thus the patient after the examination of the magnetic resonance apparatus, without first separate the storage part again. This leads to an extension of the examination period.
It is therefore an object of the invention to provide a storage device on which a patient is comfortable and safe both for preparation of an examination and for examination, especially his lower abdomen, can be stored himself. Further, it is an object to provide an improved patient table and a medical device with such a patient table, with which a study in a patient tunnel of the medical device easy, safe, efficient and comfortable for the patient can be prepared and performed.
The first object is achieved by a storage device

Advantages and details of the present invention will become apparent
from the embodiments described below
as well as from the drawings. The listed examples provide
no limitation of the invention. It show:
1 a schematic sketch of a medical device with a patient table and a storage device in a first position,
2 a schematic sketch of a medical device with a patient table and a storage device in a second position,
3 a schematic sketch of a storage device in a plan view and
4 a schematic sketch of the storage device in the medical device in a front view.
The figures are the same parts with the same reference numerals.
The 1 and 2 show schematically a medical device 1 with a patient tunnel T and one by means of a traversing device 9.1 from the front of the medical device in the patient tunnel T movable patient table 9 , The medical device is, for example, a magnetic resonance device with a magnet unit 3 , which surrounds the patient tunnel T radially to the axis of the patient tunnel T. In other embodiments, the medical device may be 1 also be a computed tomography device or a PET device whose gantry or detector surrounds the patient tunnel.
The patient table 9 carries in 1 a storage device 5 , The storage device 5 includes a storage board 5.1 and a sliding device 7 connected to the patient table 9 as a supporting substructure via a connecting device 9.2 connected is. The connection device 9.2 is designed such that the storage device 5 with the supporting patient table 9 is releasably connected, so that the storage device 5 from the patient situation positioning table 9 is removable. So can the medical device 1 even without the storage device 5 be used in the usual way.
For example, the connection device 9.2 advantageous as a replaceable board of the patient table 9 educated. Such exchange boards for patient support tables are known, for example, from the available on the market MR devices MAGNETOM Symphony or MAGNETOM Avanto Siemens AG, and allow a quick and convenient retrofitting of the patient table z. B. also with different essays.
Due to the solubility of the storage device 5 from the substructure 9 It is possible to have a patient outside the examination room in which the medical device 1 to prepare for an investigation by B. in a preparation room already on the storage device 5 "Probeliegen" can.
In 1 is the storage device 5 in a first position relative to the patient table 9 in which the storage device 5 at no point above the patient table 9 survives. In this position, the patient table can 9 without hesitation in each, even without the storage device 5 possible horizontal position can be traversed without interfering with the medical device 1 is to be expected, or would be on the storage device patient P exposed to a hazard. Furthermore, the patient table 9 with the storage device 5 in the first position also be moved vertically when the patient table 9 located in front of the medical device, outside the patient tunnel T. In this case, the patient table 9 together with the storage device 5 for example, lowered to a patient an upgrade and storage on the storage device 5 to facilitate. By the execution of the storage device 5 as a component, a patient can easily and in one step on the storage device 5 be stored without the special assistance of a person supervising the examination.
The storage device 5 advantageously comprises upholstery or documents 11.1 . 11.2 . 11.3 for convenient storage of the patient P. Here is the storage device 5 Advantageously designed so that a patient P stored thereon is held in the Steinschnittstellung.
The storage device 5 is on the slider 7 displaceable. It is sufficient if the storage device 5 by hand, z. B. by a person supervising the investigation, is displaced. Alternatively, a motor drive can be used, with a compatibility with the medical device 1 For example, a compatibility with a magnetic resonance device 1 , pay attention.
The storage device 5 can by means of the sliding device 7 in particular at least partially over that with the sliding device 7 connected substructure 9 , here the patient table 9 to be moved out. In this case, the storage device 5 with advantage at least as far in a second position on the patient table 9 be shifted out that a foot-side half of the storage device 5 over the substructure 9 protrudes. In this second position, therefore, the legs of one on the storage device 5 stored patient P, pushed back out of the patient tunnel T out. Optionally, in this position, the sowing of the patient P is already at least partially pushed back out of the patient tunnel T out.
To temporarily move the storage device 5 on the slider 7 to prevent, and the storage device 5 rather in a certain position relative to the substructure 9 to lock, includes the storage device 5 a locking device 7.1 for temporarily locking the storage device 5 against the sliding device 7 , Here is the locking device 7 designed so that they are the storage device 5 can releasably lock at least in the described first and second positions.
As a locking device 7.1 For example, a glide on the slider come 7 preventing, eg. B. at different locations along the length of the slider 7 firmly with the sliding device 7 or the substructure 9 and the storage device 5 connectable and detachable stopper, or a releasable latching mechanism z. B. between storage device 5 and sliding device 7 that the storage device 5 at certain positions releasably engage, into consideration.
By a procedure of the patient table 9 to the rear end of the patient tunnel T and a displacement of the storage device 5 by means of the sliding device 7 in the direction from the patient tunnel out into the second position, the storage device 5 so be positioned with respect to the medical device so that at least the foot-side half of the storage device 5 freely accessible at the rear end, outside the medical device 1 as it is in 2 is shown.
In this position, z. B. an assay device 15 without one on the storage contraption 5 Pati ducks to move, at the storage device 5 be attached. This will be related later 4 continue running.
As in 3 as can be seen, the storage device comprises 5 in her foot-side half a recess 19 , Here is the recess 19 across the width of the storage device 5 centrally located. In particular, the recess 19 such on the storage device 5 arranged that the recess 19 through the storage board 5.1 the storage device 5 through access to the trunk end of a stored on the storage device patient P, in particular provided at the trunk end body openings granted. For clarity, a patient P is indicated by dotted lines in FIG 3 indicated.
The recess 19 runs the length of the storage device 5 advantageous to the middle of the storage device 5 where approximately the torso end of one on the storage device 5 stored patient P is located. Thus, the storage device 5 in the second position described above so far on the supporting substructure 9 , here the patient table 9 , that shifted the recess 19 in a horizontal plane next to the substructure 9 located.
For a particularly easy access to the trunk end of the patient P, the recess runs 19 furthermore advantageous over the length of the storage device 5 to the foot-side end of the storage device. This will through the recess 19 not only from below the storage device 5 Access to the on the storage device 5 granted patients, but also from the foot-side end of the storage device 5 out.
Here is the recess 19 advantageously slot-like in the foot-side half of the storage device 5 educated. This is the recess 19 on the one hand easy to manufacture, and on the other hand particularly easy to understand.
Possible dimensions of the recess 19 are here z. B. a width of at least 10 cm, typically 15 cm or more. The width of the recess 19 is at least as large as a width of the examination device 15 , The length of the recess 19 is advantageously between 50 cm and 100 cm, z. B. corresponding to an expected leg length of a patient to be examined. A typical length of the recess is thus z. B. at more than 80 cm.
As already in 2
shown in the recess 19
a medical examination device 15
be attached. In this case, the examination device comprises 15
an endorectal and / or endovaginal insertable into the lower abdomen of the patient P device 15.1
and a holding and guiding device 15.2
for holding and guiding the insertable device 15.1
, Such mounting and guiding devices 15.2
for endorectal or endovaginal insertable medical devices are known (see, for example, the already cited abstract and poster "MRI-guided prostate biopsy in two different standard 1.5 T scanners using an endorectal biopsy device", Proc. Intl. Soc. Mag. Reson. Med. 14 (2006), page 1446
). Therefore, a more detailed description is omitted and only pointed out that the mounting and guiding devices 15.2
for use with a magnetic resonance device MR-compatible, ie in particular non-magnetic, must be performed.
At the examination device 15 For example, it may be a biopsy device 15 with and biopsy needle 15.1 or, in the case of a magnetic resonance device as a medical device 1 to a local coil device 15 with local coil 15.1 , act. With such a biopsy device 15 In particular, endorectal biopsies of the prostate or of the (end) intestine are accompanied by image monitoring by means of the medical device 1 for both the patient and a user performing the biopsy through the placement in the recess 19 comfortable and thus also effective. Also endovaginal biopsies z. As the uterus or ovaries are with the storage device 5 and the examination device 15 facilitates and accelerates the investigation as a whole.
In an embodiment in which the medical device 1 a magnetic resonance device 1 is, the examination device can 15 advantageously an endorectal and / or endovaginal in the lower abdomen of a on the storage device 5 insertable device 15.1 comprising both a biopsy needle and a local coil for accurate image monitoring of the biopsy.
Especially in the 2 and 4 The medical examination device can be seen 15 through against the patient table 9 shifted storage device 5 such in the area of the recess 19 arranged, and with in the area of the recess 19 at the storage device 5 arranged fasteners 22 be attached that the entire cross-section of the patient tunnel T for the medical examination device 15 can be exploited. It stands in particular by the recess 19 and the over the patient table 9 also shifted storage device 5 the one under the Ni veau the storage device 5 lying area for the medical examination device 15 to disposal.
As a fastening device 22 come, for example, releasably interlocking or z. B. connectable by clamp clamping devices, on the underside of the storage device 5 around the recess 19 arranged brackets into consideration, with suitable, z. B. positively formed attacks the mounting and guiding device 15.2 to grab. However, there are also other fastening devices 22 conceivable.
For one by means of the medical examination device 15 to be performed and with the medical device 1 to be monitored or by means of the medical examination device 15 and the medical device 1 To be performed examination, the patient table 9 back towards the front of the medical device 1 be moved without the storage device 5 doing against the patient table 9 is moved. Thus, the area to be examined in the substructure of the patient P z. B. in a measuring volume of the medical device 1 be brought inside the patient's tunnel T to perform the investigation there.
To use in this procedure of the patient table 9 into the interior of the patient tunnel T at the storage device 5 attached medical examination device 15 safe from collision with the limit without further monitoring 21 of the patient tunnel T includes the storage device 5 furthermore advantageously a protective device 17 that are attached to the storage device 5 fixed medical examination device 15 at least partially surrounds. Such a protection device 17 can be formed in a particularly simple embodiment trough-like or U-shaped, as in the 2 . 3 and 4 outlined by dashed lines. The protection device 17 is similar to the medical examination device 15 detachable with the storage device 5 connectable. In any case, it surrounds the storage device 5 attached protection device 17 the medical examination device 15 in particular downwards, thus giving a frame for the medical examination device which can not be lowered downwards 15 in front.
After an examination with the medical examination device 15 and the medical device 1 becomes the medical examination device 15 again from storage device 5 removed and the storage device 5 can with the sliding device 7 moved to the first position described above, where they are with the locking device 7.1 can be locked to in this position with the patient table 9 on the front of the medical device 1 to be pulled out of the patient tunnel T.
Outside the patient tunnel T, the storage device can now 5 with the patient table 9 be lowered again to facilitate the patient P to dismount.
